1.0 Document Overview The Domain Tables Technical Reference is intended as a central repository for all allowable domain values referenced in spatial databases in the Guidelines and Standards for Flood Risk Analysis and Mapping. All domain tables and their allowable values are listed in alphabetical order in this document.
Mapping Partners must use this document as a reference to identify valid values for appropriate domain tables in databases.
Note: In the “Applies to Database Schema” column:
• “FIRM” indicates that a value is only acceptable in the Flood Insurance Rate Map (FIRM) Database schema.
• “FRD” indicates that a value is only acceptable in the Flood Risk Database (FRD) schema.
• “FIRM, FRD” indicates that it is acceptable for both the FIRM and FRD database schemas.
• “NFHL” indicates this domain value is only used in the National Flood Hazard Layer (NFHL) database schema.

1. The CONTAINED IN CHANNEL or CONTAINED IN STRUCTURE zone subtypes should only be used if the flooding associated with these channelized structures or other structures is large enough to show as an area. These features should also be drawn as structures in S_GEN_STRUCT and coded appropriately there.
2. Formerly “PROTECTED BY LEVEE”.
3. “AREA OF MINIMAL FLOOD HAZARD” terminology is used by the Code of Federal Regulations CFR 64.3 to define an unshaded Zone X.
4. Types of FLOODWAY. Other than the generic “FLOODWAY” subtype, these are areas in which a community enforces more restrictive criteria for floodplain management than the minimum requirements of the NFIP.
5. “DENSITY FRINGE AREAS” are a floodway type specific to the State of Washington used in communities where encroachment and storage-volume reduction are specified in locations of zoned development, as opposed to the traditional equal conveyance reduction floodway.

6. These subtypes are typically symbolized as shaded Zone X. “1 PCT FUTURE CONDITIONS” is a subtype of Zone X and are labeled ZONE X FUTURE on the FIRM panel.
7. These subtypes are only used in coastal areas to specify riverine or coastal flooding. More information on these zones can be found in the FIRM Database Guidance document.
